fo all whom it mcg/ concern:

Be it known that l, CHARLES OSCAR ERIC- soN, a citizen of the United States, and a resident of Helmetta, Middlesex county, New Jersey, have invented a new and useful improvement in Fuel-Oil-Gas Mixers, of which the following is a full, clear, and exact description.

My invention relates to improvements in fuel oil gas mixers, and the general object of my invention is to produce a simple attachment which can be applied to various forms of internal combustion engines so as to prevent too rich a mixture from passing to the cylinder from the carbureter. It is well known that if the gas mixture is too rich, unsatisfactory results are obtained, and especially if any of the fuel oil passes without vaporizing into the cylinder, the result of the rich mixture being that slow and incomplete combustion rather than explosion takes place in the cylinder and the cylinder becomes foul, the sparking devices get short circuited, the engine does not run prpperly, and there is a great waste of fuel. y invention is intended to obviate these difliculties, and in a very simple manner break up any heavy or rich mixture, and especially any liquid, so that it will be thoroughly mixed before passingto the engine cylinder.' My invention is further intended to produce a device which will never need any attention and can be easily applied at little expense to any ordinary type of engine and carbureter.

Referenceis to be had to the accompanying drawing` forming a part of this specification, in which similar reference characters indicate corresponding parts in the view.

The ligure is a central longitudinal section of the structure embodying my invention, showing its application to a carbureter and manifold intake of an engine cylinder.

A short pipe connection 10 is made between the carbureter and engine cylinder, and ll have shown the pipe provided with flanges 11 and 12 adapted to connect with corresponding parts of the carbureter 13 and the manifold inlet pipe 111. Obviously the particular way of inserting the Vaporizing device can be departed from, however, and it can be applied to any convenient form of pipe. As shown, however, the structure is provided with a ring 15 at its inner end which lits in a corresponding re- Speccaton of Letters Patent.

Patented (let. 11, 1921.. 191e. serian no. 301,448.

cess 16 at the end of the pipe connection 10, so that the inner surface of the rino' will be flush with the inner surface of the flange 12, and so when the flange 12 is secured to the flange of the manifold inlet pipe 14:, the ring 15 will be bound in place. To the ring 15 is attached an imperforate helical blade 17 which extends in the form of a screw longitudinally of the pipe 10, and is secured to the stiffening rod 18 extending through the center. blade or screw is attached to the screen 19 which thus forms a cylinder inclosing the helical blade, and this fills the inner end of the pipe 10, leaving a gap 2O between the screen cylinder 19 and the inner wall of the pipe 10. By leaving this gap or space 20, the drops of liquid broken up by the screen will have a chance to vaporize and expand so as 'to enter the cylinder suitably mixed. fhe inner end of the pipe is preferably tapered as shown at 21 so as to leave an orifice which will just be filled by the screen cylinder 19.

.llt will be noticed therefore that when the mixture flows from the carbureter it will pass through the cylinder 19, following the spiral blade 17, which should'have a capacity substantially equal to the cylinder intake, and as it rushes in with great velocity, the blade 17 will impart a rotary centrifugal motion to the inflowing mixture and the heavier' parts due to centrifugal force will be thrown against the screen 19 thereby breaking up any liquid or semi-liquid matter so that it can be properly mixed before passing to the engine. lt will be noticed, therefore, that with 'this attachment only a proper mixture not too rich in oil can pass through, and as a result the engine troubles above referred to are obviated and great saving in fuel is effected. l

l have shown a convenient means of supporting the screen cylinder with its spiral blade in the path of the fuel which passes to the engine, but it will of course be understood that this structure can be arranged in other ways if desired, and if it is necessary to suit particular conditions, without affecting the invention, the important thing being to have the screen cylinder with its blade held longitudinally of the flow of fuel so that the latter will pass through the device in a manner to have the heavier portions thrown against the screen 19 and thereby broken up and gasified. Attention is called The outer edge of the helical 10 extending longitudinally of the pipe and having a flange fitting in the aforesaid recess Whereby the cylinder body is spaced apart from the Wall of the pipe connection, and a stationary imperforate helical blade extending longitudinally through the cylin- 15 der.
